Description
Japanese Astilba is a perennial herb that belongs to the Saxifrage family. Today, there are more than 200 varieties of this shrub, each of which is characterized by its own color, splendor of flowering, structure and growth. Herbaceous plants of this type are intended for open ground, since their height can reach 80 cm, which does not allow them to be grown indoors. Japanese astilbe is distinguished by small but dense leaves that have pronounced patterns. Unlike other types of astilbe, in Japanese during flowering, a few buds of a pink or snow-white shade appear, which, even after complete drying, do not lose their shape and continue to decorate the garden plot.
The flowering period for the plant usually begins in June and lasts until September. At this time, flowers are formed on the bushes, formed into panicles from 10 to 50 cm long. They have a delicate aroma, similar to bird cherry.
After flowering, the fruits ripen, boxes with small seeds inside appear in place of flowers. Japanese astilbees of lilac and red shades look especially beautiful in landscape design, they are originally complemented by dark zilon openwork foliage.
With the onset of cold weather, the ground part of the shrub dies off, the root system is strengthened for wintering and with the arrival of spring is ready to give new offspring. Every spring, buds develop on the upper part of the roots, which are capable of giving an increase per season from 3 to 5 cm, while the rhizomes themselves in the lower part die off over time.
To ensure the normal development of the flower and the formation of new buds, immediately after dying off, the ground part is cleaned and the site of the landing pit is covered with a soil substrate. Astilba Japanese, as a rule, is planted in flower beds with Siberian iris and fern. This allows you to create original compositions in landscape design.

Care
